VESA announces Mobility DisplayPort preview at CES

We haven't heard a peep about Mobility DisplayPort or MYDP for short, for nearly a year, a display interface standard that's intended for mobile devices such as smartphones and tablets. MYDP combines DisplayPort and USB connectivity over a single connector, much like MHL except for the small fact that MYDP has the blessing of the VESA standards organization.

We haven't heard a peep about Mobility DisplayPort or MYDP for short, for nearly a year, a display interface standard that's intended for mobile devices such as smartphones and tablets. MYDP combines DisplayPort and USB connectivity over a single connector, much like MHL except for the small fact that MYDP has the blessing of the VESA standards organization.

MYDP offers a lot of advantages over MHL, for starters it supports DisplayPort 1.2. This small fact allows for 4k x 2k resolution at 60Hz, multi-stream support, panel self-refresh, 1080p 3D video, 7.1-channel HD audio support and data rates of up to 21.6Gbps. In all fairness most of these things are overkill for today's mobile devices, but it's at least good to know that it's there for future devices, especially as DisplayPort is meant to be the display interface for this century and maybe even the next.

The downside of MYDP in consumer devices is the fact that DisplayPort connectors aren't found on your average TV, although more and more computer displays are starting to adopt the interface. As DisplayPort is using a different kind of signalling that HDMI and DVI active adapters are needed, such as the one pictured above and these are significantly more costly than a passive adapter. That said, with a bit of luck well see DP++ support which means that passive adapters can be used for resolutions up to 1080p, but this will require additional support inside the device itself.

As MYDP is only a proposed standard at this stage, it'll need to have the VESA members agreeing upon its implementation, although the standard is already backed by companies such as STMicroelectronics, ST-Ericsson and Analogix. MYDP also has the advantage of being royalty free, unlike HDMI. VESA's demo at CES should hopefully help push the standard forward, but with MHL already being adopted in a wide range of consumer devices, MYDP is fighting an uphill battle.
